States Patent TURRET WHEEL FOR WRAPPING MACHINES Milan Mateyka, Union, and Martin E. Leszczynski,

Jersey City, NJ., assignors to Scandia Packaging Machinery Company, North Arlington, N.J., a corporation of New Jersey Filed Aug. 16, 1967, Ser. No. 661,072 Int. Cl. B65b 11/30 US. Cl. 53-234 Claims ABSTRACT OF THE DISCLOSURE The invention involves rotary turret wheels mounted in the path of travel of packages and wrappers and these wheels have radial pockets which receive the packages and wrappers. Each pocket has at the outer side a tucker blade which is hinged and is held in position by a latching plate. In order to facilitate the removal of an improperly wrapped package the tucker blades can be manually swung outwardly after releasing the latching plates.

This invention relates to wrapping machines and particularly to the construction of turrets for use in such machines.

The object of the invention is to provide in a wrapping machine having turret wheels means for facilitating the removal of improperly wrapped packages from the wheel.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application and in which:

FIG. 1 is a plan view of a wrapping machine illustrating a turret wheel embodying the invention;

FIG. 2 is an end elevation of one of the turret wheels;

FIG. 3 is a side elevation showing two turret wheels facing each other and spaced to receive packages and wrappers;

FIG. 4 is a sectional-elevation taken substantially on line 44 of FIG. 2 illustrating one of the tucker blades swung outwardly to permit easy removal of the package and wrapper.

FIGS. 5, 6, 7 and 8 are perspective views illustrating the successive folds in the wrapper as it passes through the machine.

In the machine illustrated in the drawings two turret wheels are mounted in spaced relation as shown in FIG. 3 and each wheel has a radial series of inwardly facing pockets 10, 11, 12, 13, 14 and 15. Each pocket has fixed side walls 16 and 17 and is open upon the inwardly facing side. The wheels are mounted for intermittent rotation and the packages 20 are fed along a platform bottom by cross rods 21 which extend between parallel chains 22. As the turret wheels stop in their intermittent rotation the wrappers 23 are fed across the path of movement of the packages and are pushed into the pockets so that the wrapper will extend around the upper and lower face of the package and beyond the entrance of the pockets as shown at 24 in FIG. 1.

In order to tuck the inner ends of the wrapper against the ends of the cakes or bars each pocket has at the outer end thereof a tucker blade 25 which is hingedly mounted at 26 on a collar or hub 27. As shown in the figures, the tucker blade member extends at least a portion along one side of each of the pocket members. In this specific embodiment, the tucker blade member extends the entire length of each of said pocket member.

In order to hold the blades in operative position such I as shown at the :bottom in FIG. 4, locking plates 30 are slidably mounted on the outer surface of the tucker blades and are frictionally held in position by screws 31. When these plates are pushed inwardly as shown at the bottom of FIG. 4 the inner ends are locked in slots 32, thus holding the tucker blades in the position shown at the bottom in FIG. 4.

When the wrapper is improperly wrapped around the package or if for some other reason it is desirable to remove the wrapper and package, the plate 30 is moved outwardly, thus releasing the tucker plate 25 so that it can be swung outwardly as shown at the top in FIG. 4.

It will be understood that the wrappers and packages are fed into the facing t-urret wheel pockets and during this feeding movement tucks a as shown in FIG. 5 are formed in the wrapper. The outer edges of the wrapper extend beyond the outer ends of the pockets as shown at 24 in FIG. 1. As the wrapper and package move to the position B in FIG. 1 an arcuate blade 35 on an intermittently movable arm 36 engages and folds one of the projecting ends 24, the other projecting end is folded across the outer end of the cake or bar by an arcuate blade 37 mounted on an arm 38 which is intermittently oscillated to perform this operation.

This folding operation is illustrated in Pat. No. 2,400,682.

After the turret wheel has reached a position of from the receiving position shown at the left in FIG. 1, the wrappers and cakes or bars are ejected from turret wheel pockets by lugs 40 mounted on a chain 41. It will be understood that these lugs move in the path between the two turret wheels. When the wrappers and the packages are discharged from the pockets and tucks b shown in FIG. 6 are formed by means of tucker blades 42 and the end flaps are folded successively by means of folding slots 43 and 44 as shown in FIGS. 7 and 8.

It will be seen that simple and practical means has been provided for opening the outer ends of the pockets to permit release of the wrappers and packages therein when a package has been improperly Wrapped.

Although one specific embodiment of the invention has been particularly shown and described it should be understood that the invention is capable of further modifications and that changes in the arrangement and in the construction of the various parts may be made without departing from the spirit and scope of the invention.

What is claimed is:

1. In a wrapping machine having at least one turret wheel comprising:

(a) a series of radial pocket members located along the periphery of said first turret wheel,

(b) a tucker blade member located at the outer edge of each said pocket member,
